That's an aweful mindframe to have... Yes they are people and yes they need to make money. Have you ever had a salesman lie to your face about something? Sure they're people but not always the most "moral" of people...20700 is actually a very good deal!
remember, salesmen are humans too. they need income to support their family just like you. plz don't be like a cheap ass and waste their time.
i know ppl always want the best/lowest price... but come on, let the poor salesmen make some money.
